About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-50
The AirTAC SAIJ100X200-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This creates a usable stroke window of 150 to 200 mm, letting you dial in the exact end position at commissioning without adding external stops. The 100 mm bore delivers substantial thrust, pushing with 7068 N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This model is built with a SUS420J2 stainless steel rod for enhanced corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.
The SAIJ series utilizes a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on other variants. With a robust 25 mm rod diameter and M20x1.5 rod thread, it handles side loads well, though long unsupported strokes still require an external guide.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-50 Is Used
Machine Changeover
Dial in the exact retract position within the 150-200 mm window during product size changes without swapping out the entire cylinder.
Adjustable End Stop
Replace fixed mechanical stops with the built-in 50 mm adjuster to fine-tune the end position during initial machine commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-50 the Right Cylinder?
Select the SAIJ100X200-50 when your application requires a 100 mm bore but demands on-the-fly end-position tuning across a 150 to 200 mm window. The 50 mm adjustment range is ideal for product changeovers on a line where the exact retract distance varies by up to 50 mm.
Because this is a double-acting cylinder, the rear screw stopper and the variable air cushions only decelerate the piston at the travel end; they do not function as a lock. If your setup must hold a load vertically or resist movement without continuous air pressure, you should integrate an external rod lock or pilot-operated check valve. When replacing an ISO 15552 cylinder, match the 100 mm bore, 200 mm stroke, PT port thread, and desired mounting accessory. The 200 mm stroke is short enough that side-load concerns are minimal, but the 25 mm rod provides excellent rigidity for offset loads.

- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-50 FAQ
The maximum theoretical force at 1.0 MPa is 801 kgf.
The rear adjuster screw acts as a mechanical stop that can shorten the nominal 200 mm stroke by up to 50 mm, giving an effective travel window of 150 to 200 mm. It sets the end position but does not lock the load without live air pressure.
